No new t-shirt can feel quite as comfortable and soft as your old vintage t-shirt. If you have a new shirt that could use some softening, clothing company Octane suggest a quick bath in some salt water to fix it right up.

The process is really simple. Fill a bucket with 1 quart of water and 1/2 cup of salt. Submerge the shirt in the water and let it sit in the salt water for three days. After three days, wash it as you normally would. When you're done, your stiff new shirt will magically be as soft as your favorite vintage t-shirt.
